- My homework was to design and implement a simple social network program in Java. I should use an adjacency matrix data structure in my implementation. Write a social network program in Java. The default information for this network is stored in two files: index.txt and friend.txt. The file index.txt stores the names of the people in the network – you may assume that we only store the given names and these names are unique; and friend.txt stores who knows whom. The program must read these two files. The following section describes the format of these two files. The friend.txt takes the following format. The first line is the number of pairs of friends. Each subsequent line has two integer numbers. The first two numbers are the indices of the names. The following is an example of friend.txt:50 31 30 12 41 5 The index.txt stores the names of the people in the network. The first line is the number of people in the file; for example:60 Gromit1 Gwendolyn2 Le-Spiderman3 Wallace4 Batman5…Computer Science Done in Perl. Someone gave me a wrong/incomplete answer. Write a function, hashsum, which takes a hash reference as its first argument and an array reference as its second argument. The function should take the elements of the array and use them as keys in the hash. The values in the hash corresponding to the keys in the array should be totaled, and the sum should be returned to the user. If a key passed in the array does not exist in the hash, ignore it. Write a sample program to call this function.What is the difference between void and NULL pointers .Give suitable examples in support of your answer.Give the differences in TABULAR form.

- Can you help with with the following questions, regarding population genetics and the Wright Fisher model in python? 1. Go through the given WFtrajectory function and give a short explanation of what each line of code does. Pay attention to the variables in the function and explain what they contain. 2. Make a new version of the WFtrajectory function which does exactly the same thing except that instead of appending to a list it initialises a numpy vector with zeroes and fills the vector with a for loop instead of a while loop. Make a plot of the output from a few example trajectories.Pointer variables are just that. Why? What is "dynamic array"? What's their relationship?IN JAVAScript - Create a function that takes an object and returns the keys and values as separate arrays. Return the keys sorted alphabetically, and their corresponding values in the same order. Examples keysAndValues({ a: 1, b: 2, c: 3 }) → [["a", "b", "c"], [1, 2, 3]] keysAndValues({ a: "Apple", b: "Microsoft", c: "Google" }) - → [["a", "b", "c"], ["Apple", "Microsoft", "Google"]] keysAndValues({ key1: true, key2: false, key3: undefined }) [["key1", "key2", "key3"], [true, false, undefined]]
- When it comes to data types, what are the pros and downsides of using user-defined ordinal kinds? An associative array has many benefits and downsides, which we will discuss in detail below.Focus on dictionary methods, use of functions, and good programming styleFor this assignment, you will create a glossary (dictionary) of technical terms and definitions. It will be set up as a Python dictionary structure. The file glossary_starter.py is a complete starter framework for the assignment. It includes some initial values for the dictionary. It is long because most of the code has already been written for you.Your task is to complete the five individual functions for adding and deleting terms, looking up terms, listing them, and printing out both the terms and definitions. These functions are all short, just a couple of lines, and use basic dictionary methods and techniques. Here is some sample output. Glossary system 1) Add a term 2) List terms 3) Get a definition 4) Delete a term 5) Print out dictionary 6) Quit Enter your choice: 2 argument dictionary hashmap list set 5 terms Glossary system 1) Add a term 2) List terms 3) Get a definition 4) Delete a term 5) Print…Focus on dictionary methods, use of functions, and good programming styleFor this assignment, you will create a glossary (dictionary) of technical terms and definitions.
